To draw an image onto a control, you should override that control's OnPaint() method.

C#

override void OnPaint(object sender, PaintEventArgs e)
{
    System.Drawing.Image image = _dictionary[keyToTheImage];

    // Used to place image onto center
    int imageWidth = image.Width;
    int imageHeight = image.Height;

    e.Graphics.DrawImage(
        image,
        new RectangleF(
            (this.Width - imageWidth) / 2F,
            (this.Height - imageHeight) / 2F,
            imageWidth,
            imageHeight
        )
    );
}

Solution 2

C#

string itemPath = null;
foreach (var item in arrAllItems)
{
    if (itemC[i] == item.id)
    {
         itemPath = item.imgPathLarge;
    }
}

by using these code i am able to get the image from the database into the new canvas
